Improvement in buckles



UNITED STATES PATENT OFFICE.

THOMAS P. MARSHALL, OF TRENTON, NEIV JERSEY.

EMPROVEMENT EN BUCKLES.

Specification forming part of Letters Patent No. 24,649, dated July 5, 1859.

To all wlwwt it may concern:

Be it known that I, THOMAS P. MARSHALL, of Trenton, in the county of Mercer and State of New Jersey, have invented a new and Improved Buckle; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

Figure l represents a longitudinal vertical section of a strap, the two ends of which are secured together by my buckle. Fig. 2 is a plan or top view of the same with the ends apart.

Similar letters of reference in both views indicate corresponding parts.

This invention consists in arranging one part of the buckle in such a manner that it slides easily on the strap, which is kept in the same by the action of a spring, so that it can adjust itself to any length, and the two parts are united by means of a slot in the movable part, the largest portion of which is covered from below by a spring-platform, so that the other part of the buckle, which is firmly secured to the end of the strap and which forms a double nose, can be depressed in said slot, and that when thus depressed it is hooked in the same by the said spring-platform, which is so arranged that it can be depressed by means of a rod which extends from the same a little beyond the side of the buckle, whereby the stationary part of the buckle is freed.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents a small case cast of metal and open at one end, and the other end is provided with a slot c., which is large enough to admit the strap for which the buckle is to be used. A flat spring l) is secured to the upper part of the case A, which depresses the strap on the lower portion, which may be perforated in order to save metal.

The upper part of the case A is provided with a slot B, which consists of a larger 0blong part c and of a smaller portion c', and a platform CZ, which is hinged to a pin e, covers the larger part c of this slot. The pin e is iirmly secured in the sides of the case, and a spiral springf is arranged on this pin in such a manner that it keeps the platform d up against the under side of the slot cp This platform may, however, be depressed by means of a rod g, which is rigidly attached to the same and which extends a little beyond the side of the case, so as to forni a button which moves up and down in a slot in the side of the case A.

The other part C of this buckle is firmly secured to the end of the strap, as clearly shown in Fig. 2, and for this purpose this part is provided with a rounded pin 71 which is locked in a loop formed by the. end of the strap, and attached to this piu is a nose 1', which is provided with two notches j, and the nose is of such a size that it passes freely through the larger part c of the slot B in the case A, and the notches j are of such adepth that the solid portion of the nose contained between the same can be brought into the smaller part c of the slot B, in which it. is confined by the platform d.

The operation is as follows: If the end of the strap with the nose i is passed around a post and the nose depressed in the slot B, where it is locked in by the action of the spring-platform d, any strain exerted on the loose end of the strap brings the buckle close up lto the post, and the strap is tied to the same. In order to loosen it the platform CZ is depressed by means of the button g, and the nose t can be pushed back from the smaller part c of the slot B to the larger part c, so that it can be taken out.

This buckle is of particular convenience for halters or similar straps where it is desirable to secure the two ends together quickly, and so that the strap is firmly drawn up to the post or tree to which it may be tied.

What I claim as new, and desire to secure by Letters Patent as a new article of manufacture, is-

A buckle constructed of a sliding case A, with the platform d and slot B, in combination with the nose l17, and otherwise arranged as herein set forth.
